remove quote symbol in root_path='/media/jsu/F81CA38A1CA3430C/nuScences/NUSCENES_TRAINVAL_DATASET_ROOT/'

QYWT commented 4 years ago

I have removed the quotes from the command, but the error still exists. jsu@214-4:~/Det3D$ python tools/create_data.py nuscenes_data_prep --root_path=/media/jsu/F81CA38A1CA3430C/nuScences/NUSCENES_TRAINVAL_DATASET_ROOT/ --version="v1.0-trainval" --nsweeps=10

@QYWT Same problem, have you solve this problem?

tianweiy commented 4 years ago

@lqzhao @QYWT Change the https://github.com/poodarchu/Det3D/blob/ed0f5418c6c9b06fc5f4b73888703a9a19c2947f/tools/create_data.py#L26 to 

        Path(root_path) / "infos_train_{:02d}sweeps_withvelo_filter_True.pkl".format(nsweeps),
tianweiy commented 4 years ago

@poodarchu can you fix this? I changed the info name to reflect the filtering.

QYWT commented 4 years ago

@tianweiy Thank you for your advice. I have another question, where and how should I update dataset setting and path? Update dataset setting and path dataset_type = "NuScenesDataset" n_sweeps = 10 data_root = "/data/Datasets/nuScenes" db_info_path="/data/Datasets/nuScenes/dbinfos_train.pkl" train_anno = "/data/Datasets/nuScenes/infos_train_10sweeps_withvelo.pkl" val_anno = "/data/Datasets/nuScenes/infos_val_10sweeps_withvelo.pkl"
